parat-us, 0r apparatus for singeing hosiery..

but it will be understoodthat the ninvention can be used for eonveyinfl, a carrier t'or any purpose where it is desired to drive the carrier in an endless path,

l In the accompanying dralvingsz-Figure4 l, 1s a plan vieu' of a table slnnving the carriers in position; Fig. 2, is a plan view showing the cams for traversing the car' riers;` and Fig. 3, is a transverse sectional View on the line 3 3. Fig. 1. l is' a table or other support. having a quadrangular slot '2 therein, forming a guidevvay.

.3, 3 are carriers adapted to the guideway, the face of the carriers being square so .that While the carriers are t'ree to'slide inl theguldeway, they are heldI from turning,

therein. The guideway has upper and lowei` tla-ngesto hold the carriers vertically. In the present instance,v depending from each carrier is a spindle 4 having a roller arranged to be engaged by driving cams. The carrier may lsupportl any suitable device, according to the use to which the invention is'ap'plied. Underthe table, in the present inst-ance, are four shafts G, 7, S and 9, geared together as shown in Fig. Q, and adapted to bearings 10 secured in any suitable man- 'ner .to the frame of the table. 11 is a scroll camon the shaft 6 extending under the for- 'Ward guideway of the table.

12 is a longitudinal cam mounted on the shaft 7, and this cam terminates short of the inner` end of the shaft.

13 is a cam onthe shaft 8 extending praetically the full length of the Way in the table, and 14 is a short cam on one end of the sha-ft 9 for lremoving the carrier freni the control of the last mentioned cam. .Also on this shaftis a long cam 15 se arated from the short cam by a space. :By is construction the carriers are under the control ot' the cams except at t\vo pointswhere they accumulate until one carrier pushes the other into they path of a cam. rlhis is particnlarlv used, in drying hosiery -Where part o'tl the table is covered by a drying chamber, so that the hosiery 'forms are ted into the chalnberand allowed to remain there for a certain length of time.'

It will he noticed that one end of each longitudinal cani overlaps the ends of the 'forward transverse Cain7 so that the carrier is not released by one cam until the other cam hasengaged it. This construction prevents the accidental movement ot the carriers out of the path ot the cams and insures the proper movement ot all the carriers. This saine construction is used where the rear transverse cani delivers the carrier to the short longitudinal cam.

It will be noticed that the hubs ot' the bevel gear wheels are extended'and are recessedat 16 for the free movement. of the cams as they rotate. so that the end ofthe cam can properly engage the carriers.

l. The combination of atable having angular guideways therein; a' carrier arrangedl to travel in the guideways: and a cam undereach section of the guideways -t'or traversingthe carrier in a particular guideway; the calnsbeing so arranged that the carrier will be' transferred from one Section ot' the guideways to another. causing the carrier to travel in a continuous path.

2. The combination of a table in which there is a quadrangular guideway; carriers mounted in the guideway; four shafts under the table; and a cam on each shaft engaging the carriers, so that, as the shafts rotate,

the carriers will be fed forward in an endless path. y"

3. The combination ot a table' having a qnadrangular guideway therein; carriers mounted in the guideway; four cam shafts under the table geared together; and scroll cams on each shaft, the ends of some of the cams overlapping .the 'ends of others so las. toretain the control of they carrier while `being traversed at a. corner.

4. The combmatlon 1n a table having a quadrangular guideway therein; of a series of carriers mounted inthevguidevvay; four shafts vgeared togethergceroll 'cams on the iransvers shafts exunding the ful length of the guidewaly; Withfjscroll cams on the longitudinal .shaftrs stopping'shor't of die inner endsof sind shafts; and a short scroll cam On yth'-extreme end of One o f'said shafts 'SQ that., 'as themen-fiers are talvez-sed over the gu'deway, they will 'dwellat .two point in their travel.
